When an obstruction is present also in the upward area
(1)When one outdoor unit is installed individually
The dimensional relationship between H, L and A is as shown in the
table below.
NOTE
• Close the area under the frame so that the outlet air does not bypass
there.
(2)When only two outdoor units are installed side by side
The dimensional relationship between H, L and A is as shown in the
table below.
NOTE
1. Close the area under the frame so that the outlet air does not
bypass there.
2. Only two outdoor units can be installed side by side.
(D) When outdoor units are stacked
(1)When an obstruction is present on the air outlet side
NOTE
1. Only two outdoor units can be stacked.
2. About 4 in. is required as the drain piping size for the upper out-
door unit.
3. Close the area Z (gap between the upper outdoor unit and the
lower outdoor unit) so that the outlet air does not bypass there.
(2)When an obstruction is present on the air inlet side
NOTE
1. Only two outdoor units can be stacked.
2. About 4 in. is required as the drain piping size for the upper out-
door unit.
3. Close the area Z (gap between the upper outdoor unit and the
lower outdoor unit) so that the outlet air does not bypass there.
(E) When outdoor units are installed in rows (on the rooftop, etc.)
(1)When one outdoor unit is installed in each row
(2)When two or more outdoor units areinstalled side by side
The dimensional relationship between H, L and A is as shown in the
table below.
